Just visited NUMISMATA 2026 in Munich, Germany.
It is one of the bigger shows in Europe. Although the venue is smaller than say the World Fair of Money, it still is a very large hall. Lots of dealers from all over Europe and a few from the US as well.
The most popular product appeared to be 2 Euro coins as almost any seller had these on offer. There was also lots of paper currency, mint sets, and modern silver coins. I did not see as many classic silver coins as you have at American coin shows.
Unfortunately, on Saturday morning it was super crowded with barely any space to move. Another disappointing thing was that many attendees and dealers were rather rude and often elbowed themselves into place. Dealers rarely acknowledged you or said "hi". Again, very different from US coin shows.
In the end I stayed about 4 hours and was able to purchase a few hard to find coins for my sets. I will post these later.
